SOLID POLYMER ELECTROLYTE MEMBRANE AND METHOD FOR MANUFACTURING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a solid polymer electrolyte membrane with a high electric conductivity capable of being mass-produced while reaction control being comparatively easy, and to provide a method for manufacturing the same.

SOLUTION: The method for manufacturing solid polymer electrolyte membrane includes: a membrane forming step of forming a precursor film using a prepolymer solution in which a prepolymer is dissolved or dispersed in a solvent or a prepolymer melt in which the prepolymer is melted; and a crosslinking step of crosslinking directly among the prepoymers in the precursor film or through a crosslinking agent introduced in the precursor film at a time of forming film or after forming film. The solid polymer electrolyte membrane obtained by such the method is also provided.
